RADIATOR FOR STOVES.

SPECIFICATION forming part of Letters Patent N 0. 738,222, dated September 8, 1903. Application filed March 9,1903. Serial No. 146,859. (No model.)

To all whom it may concern:

Be it known that I, JOHN G. MEISTER, a citizen of the United States, residing at Sterling, in the county of XVhiteside and State of Illinois, have invented certain new and useful Improvements in Radiators for Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanyingdrawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to radiators for stoves, and comprises a heat-chamber immediately beneath a central aperture adapted to be heated therefrom and a system of radiation by means of which the maximum amount of heat in a current of hot air may be diffused therefrom.

Another advantage of my invention consists in the arrangement of the parts so as to present no flat surface for the accumulation of ashes or soot.

Many devices of this class cannot be successfully used in connection with stoves in which soft coal is used for fuel on account of the tendency of the radiator to become clogged with the soot and the difficulty of cleaning the same therefrom. This is specially the case in radiators constructed with vertical tubes fixed at each end in a head or drum. In my device all of the inner walls or surfaces upon which the soot might gather incline downwardly, so that a slight jarring of the radiator will dislodge any accumulation contained therein and compel the downward movement of the soot through and out of the radiator.

In the drawings, Figure 1 is a front elevation of my device. Fig. is a vertical section thereof looking toward the rear wall, showing the interior arrangement.

The radiator is formed of two circular walls 1 and 2, a peripheral wall 3, and an inner wall l. There is thereby provided a central aperture 5, having at the bottom a fiat seat 6, forming the lower part of the wall 4. Upon the seat 6 may be placed a kettle or other vessel containing liquids or dishes with food which it is desired to heat or keep warm. Projecting downwardly from the lower side of the flected in all directions.

seat (3 is a pair of wing partitions 7 7,reaching from the front to the rear wall of the radiator. These wings or deflectorsl' are arranged on opposite sides of the inlet 9 and are pref= erably inclined outwardly in opposite directions, whereby the heat will be deflected downwardly away from the inlet, and thus preventing the same from interfering with the incoming heat. The lower ends of these wings lying adjacent the wall 3 form narrow passages 3, which prevent the heat from passing below the base 6 too rapidly.

The radiator is divided by the aperture 5 into two semicircular passages, each of which is provided with tubes or pipes 8, arranged in two spaced-apart circular series, the pipes of one series being staggered with relation to the pipes of the other series to cause the ascendin g current of heated air to alternately strike against the outer and inner walls and 4, and, further, as will be observed by reference to Fig. 2 of the drawings, the upper pipes 8 and 8 respectively, of the outer series are arranged in approximately horizontal alinement on opposite sides of the outlet 16, whereby the heat after making a tortuous passage between the lower pipes will strike the same and be forced downwardly into contact with the top of the wall 4 before passing through said outlet. At the bottom and top, respectively, of the radiator are connections 9 and 10,by means of which the radiator can be suitably located upon a stove or between two joints of the pipe thereof.

Vhen the stream of hot air is first introduced into the radiator, it strikes against the lower side of the seat 6, being thereby de- The progress of the heat is retarded by the partitions 7, which in conjunction with the walls 1 and 2, seat 6, and lower wall of the radiator establishes a heatchamber just beneath the seat 6, in which chamber a high degree of temperature is at all times maintained while the radiator is in operation. After passing around the partitions '7 the current continues upwardly through the radiator, as indicated by the small arrows in Fig. 2. At each point where a tube 8 is interposed the flow of heat is obstructed, a portion thereof being refracted through the inner or outer wall of the device which is in proximity to such tube. The remaining heat follows the diverted current toward the next succeeding tube 8. At each contact with one of the tubes a portion of the heat is diffused through the walls thereof, and it will be seen that during the progress of a current of hot air through the device there is radiation through the seat 6, the front and rear walls 1 and 2, the outer and inner walls 3'and 4, and the tubes 8. By the time the stream of air reaches the upper part of the radiator the greater part of the heat has been extracted therefrom. The partitions 7 serve the additional purpose of bracing the walls 1 and 2 against being warped by the action of the heat, in that portion of such walls where the greatest danger of such warping exists, on account of the greater expanse of metal and the greater heat of the current at that point.

Like most devices of this class, my invention is preferably constructed of sheet metal.

In case of any accumulation of soot a slight jarring of the radiator will result in the dislodgment thereof and will cause such soot to sift downwardly through the device and out through the pipe at the bottom thereof. When the radiator is detached from the pipe or stove the cleaning thereof is a still easier matter.

lVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is

A device of the type set forth, comprising circular end walls formed with openings, a peripheral wall of approximately circular contour in cross-section secured to said end walls and being formed with inlet and outlet openings at diametrically opposite points, an inner Wall spaced from said peripheral wall and being secured to said end walls around the openings thereof, outwardly-inclined wings secured to the base of said inner wall, said deflectors extending in close proximity to the said peripheral wall on opposite sides of the inlet thereof, and two spaced-apart series of pipes arranged between said inner and peripheral walls above said wings and having their ends extending through said end walls, the pipes of one series being staggered with relation to the pipes of the other series, and the two upper pipes of the outer series being arranged on opposite sides of said outlet, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
